Sustainability
Compared to rural agriculture, urban agriculture (UA) has some distinct features (e.g., the limited land access, alternative growing media, unique legal environments or the non-production-related missions) that encourage the development of new practices, i.e., “novelties” or “innovations”. This paper aims to (1) identify the “triggers” for novelty production in UA; (2) characterize the different kinds of novelties applied in UA; (3) evaluate the “innovativeness” of those social, environmental and economic novelties; and, (4) estimate the links between novelties and sustainability.
